Title: Improvements in or relating to beam-splitting devices
IPC: G02B27/28
Filed: 1951-11-09
Abstract: 706,806. Optical apparatus. LEITZ GES, E. Nov. 9, 1951 [Nov. 16, 1950; Aug. 27, 1951], No. 26258/51. Class 97(1) In a beam splitter, particularly for a binocular microscope, including a semi-transparent reflecting surface for dividing the beam, to ensure equality of the components of the two resultant beams polarized, parallel and perpendicular to the plane of incidence, the thickness of the semi-reflecting layer is so chosen that the product of the intensities of the components of the reflected and transmitted beams polarized parallel to the plane of incidence is equal to the product of the intensities of the components of those beams polarized perpendicular to the plane of incidence, and either suitable polarizers are placed in the beams to equalize the component intensities or the transmitted beam is reflected by a further similar semi-reflecting surface, and the reflected beam is transmitted by a further similar semi-reflecting surface. Fig. 4 shows an arrangement in which the beam transmitted by the semi-reflecting surface 1 is reflected by a further semi-reflecting surface 2 and a reflector 3 to emerge with the components polarized parallel and perpendicular to the plane of incidence of equal intensity. The beam reflected by the surface 1 is transmitted by a similar surface 5, after reflection at a surface 4 and emerges similarly with components of equal intensity.

Abstract: <PICT:0711915/III/1> <PICT:0711915/III/2> An apparatus for coating the inside and outside of tubes or the like with a coating of tar or like material comprises means for heating the tubes prior to coating, means for coating by immersion in a bath and means for draining off the sulplus material and for drying the coating, wherein the tubes pass singly through the apparatus in an uninterrupted flow, through the heating means in horizontal positions, and through the coating means, draining means and drying means in inclined positions.  The tubes are deposited on a track 3 (Fig. 1) and collected singly by means of the conveyer 4 and are carried horizontally in a number of vertical paths through a tower pre-heating means 1 having a heating device 2.  When the tubes are brought to the required temperature they are removed from the lower end of the last path by a horizontal conveyer 5 situated in a heat insulating housing and carried into a chamber 6, heated by waste gases from the preheating tower 1, where a double-chain conveyer 7 collects each tube 8 and holds it at an angle in a frame 9 (Fig. 2).  The tubes thus pass singly into an immersion bath 10 (Fig. 1) and then enter a number of substantially vertical tracks where the surplus coating material drains into a trough 11. The tubes are then conveyed through drying means in vertical tracks where they are dried by cold air fed from both sides by fans 12.  At the exit end the tubes are deposited on a track 13 by a tipping device (not shown).

Title: Improvements in or relating to controlling devices for fluid pressure brakes
IPC: B61H11/06
Filed: 1937-10-04
Abstract: 482,428. Fluid - friction brakes. KNORR-BREMSE AKT.-GES. Oct. 4, 1937, No. 26805. Convention date, Oct. 13, 1936. [Class 103 (i)] Controlling-device for fluid-friction brake including a pump comprises housing 3 connected to the pressure chamber of the pump by a conduit 1 and to the suction chamber by a conduit 2 and containing a piston valve 4 having a flow aperture 5 adjusted in position automatically according to the speed of the part to be braked in such a way that the pump always works against the same pressure in spite of the fall of speed of the pump as the brake takes effect. To apply the brake, the pump is clutched to the rotating part to be braked and forces fluid under pressure through conduits 1, 2 and aperture 5 and also past a valve 7, through conduits 11, 14 above the piston valve 4 which it depresses so as to restrict the passage between the conduits 1, 2. The pressure fluid also flows through conduits 11, 16 by depressing a piston valve 13 and below the piston valve 4, which in view of the restriction of area of its upper surface by the rod 6 is raised and reopens the aperture 5. Thus, as the speed diminishes, the pressure of the fluid is unable to depress the piston valve 13 in order to pass beneath the piston valve 4 and therefore the pressure above the valve 4 depresses it to a gradually increasing extent. The force against which the fluid acts to depress the piston 13 is supplied by differential fluid pressure acting on a diaphragm 23 and adjusted by means of conduits 24, 25. The underside of the valve 4 is relieved of fluid by a throttle device 18, which fluid flows partly to the suction pipe 2 by a conduit 20 and a valve 10 and partly flows to a reservoir 22. The coiiduits 15, 19 and valves 8, 9 are provided for the other direction of rotation of the pump.

Filed: 1948-10-15
Abstract: 666,572. Pneumatic separating. SAFETY CAR HEATING & LIGHTING CO., Inc. Oct. 15, 1948. [Oct. 21, 1947] No. 26850/48. Class 117.- In a method of aspirating bulk products such as grain or seed for the removal of dust, hulls and the like, a stream of the products is whirled into an outwardly moving annular stream which is then directed downwardly to an outwardly flaring path where the rotary motion of the stream is arrested and the stream is directed across an annular aspirating gap, a constant velocity air stream being passed through the product as it flows across said gap. As shown the product is fed through the top of a casing 4 onto' a conical rotor hub 10 carrying spaced spreader plates 12, 14. The plate spacing members 16 exercise an impacting action on the product, to break up and dislodge waste matter and destroy insect infestaticn, as it is whirled in a thin annular stream on to a frusto-conical downwardly convergent guide wall 22 down which it then news in a helical path and undergoes a scouring cleansing action. At the bottom periphery of the guide wall 22 the product stream drops on to an outwardly and downwardly divergent conical guide surface 34 where its rotary movement is arrested by a number of radial vanes 36 and it is caused to flow outwardly across an annular aspirating passageway 50 on to the outer surface 58 therof. The surface 58 directs the stream downwardly and inwardly across an annular aspirating air inlet into a hopper 66. The aspirating passageway 50 extends upwardly to a closed ended annular passage 67 which surrounds the conical guide wall 22 and is formed near its top with two converging tangential passageways 76 leading to an exhausting blower (not shown). An arcuate baffle plate 86 extends across the top of the portion of the passage 67 below and between the passages 72 to ensure an even flow of air at all points around the annular aspirating passage 50. In operation the product stream is subjected to a preliminary aspirating action as it drops on to the guide surface 34, by the air which accompanies it during its flow down the conical wall 22 being drawn through it into the reduced pressure space of the passage 67. The density and area of the product stream as it crosses the annular passageway 50 for the main aspirating action is so arranged that the flow of the aspirating air therethrough is maintained at the same speed as in the passageway 50. A further aspirating action occurs, but in the opposite direction, as the product stream is deflected into the hopper 66 across the annular air inlet thereabove. Specification 666,630 is referred to.

Abstract: 444,259. Fire-extinguishing by foam; spray-producers. ROSENBAUER, L., ROSENBAUER, K., HEISERER, L., FISCHER, R., WEINMEISTER, D., and HEISERER, F., (trading as FEUERWEHRGERATE-U. SPRITZENFABRIC K. ROSENBAUER), 11, Spittelwiese, Linz-on- Danube, Austria. Sept. 21, 1934, Nos. 27218 and 27219. Convention dates, Oct. 13, 1933 and May 9, 1934. [A Specification was laid open to inspection under Sect. 91 of the Acts, March 23, 1935.] [Class 47 (ii)] [See also Group XXIX] A device for the alternative projection of foam or of water jets or sprays of various forms comprises a water nozzle 38, Fig. 14, connected to a supply hose and a conical foam nozzle 41 adapted readily to be attached to or removed from the nozzle 38 by means of a ring 39. The nozzle 38 comprises a body 32 on which the nozzle sleeve 38 is adjustable, and a valve consisting of the conical member 42 on a fixed, hollow, stem 36 and the part 44 which is adjustable along the stem 36 by means of a rack 35 and pinion 34. With the parts as shown, a foaming liquid is supplied through the stem 36 by pressure or suction and is discharged, together with a water spray from the nozzle 38, into the foam nozzle 41, where it forms foam with air drawn in at the open rear end 45 of the nozzle. If the foam nozzle 41 is removed and a valve in the passage 37 closed, water alone can be projected as a solid jet, as a spray, or as a wide cone or screen by appropriate adjustments of the sleeve 38 and of the part 44 relatively to the conical member 42. With the sleeve 38 fully extended, a solid jet is obtained, quantitative control of which is effected by the part 44, which acts as a closing valve when it abuts against the periphery 43 of the nozzle outlet. For a solid jet, the part 44 should be raised to a position of continuity with the part 42. If the part 44 is withdrawn to produce a groove 46 as shown, and the sleeve 38 is retracted until the edge 43 is opposite to the groove, the water is discharged as a flat cone, due to the sharpness of the edge 43 and the shallow slope of the top 18 of the sleeve. The foam nozzle 41 may be pivoted to the nozzle 38 so that it can be swung aside to free the water jet. In a modification, the foam nozzle is removably attached to an ordinary hose nozzle delivering a solid jet, and is provided with a deflector for breaking up the jet. In another form, Fig. 1, the valve member 3, 4 is unitary and is axially adjustable in the nozzle tube 1 and the foam nozzle 12 is supported by a ring 10. In another modification, Fig. 3, the part 20 of the valve is fixed, and the stem 22 of the conical member 23 is adjustable by means of an arm 24. The Specification as open to inspection under Sect. 91 comprises also a construction in which the part 3 is screw-threaded on the stem of the member 4. This subject-matter does not appear in the Specification as accepted.
